One of the most important lesson for children is to calculate the time of their activities. They have to learn to finish their games before given time. Not considering this important issue in training, will lead the child to act in a wrong way. This may cause problems in children's communication with other children. One of the consequences of this wrong habit is clearly reflected in the children's playground and for example when playing with the swing. Like it is seen in many situations, children often find it difficult to get their turn to play with play equipment, stay in queue and the time of using equipment. For instance when a child is playing with swing,he/she takes it so long to play so that others who have been waiting for their turn to play, start to complain about their rights. In fact this wrong habit and not learning time management from the childhood, cause wrong interaction with other children. moreover they will get used to this wrong habit and stick to it in their future lives and he/she will have problems in communication with other people. Ti-Me is a play equipment Which is designed with the aim of improving this attitude and teaching children to interact better with other children in playgrounds. This concept includes some seats for waiting in lines, and a device for taking turns Which all will be placed asides other play equipment in playgrounds.
